Embodiment Construction

[0026]Some embodiments of the present invention are described in details below. However, in addition to the descriptions given below, the present invention can be applicable to other embodiments, and the scope of the present invention is not limited by such, rather by the scope of the claims. Moreover, for better understanding and clarity of the description, some components in the drawings may not necessary be drawn to scale, in which some may be exaggerated relative to others, and irrelevant parts are omitted.

[0027]With the development of capacitive sensing technology, its applications are also increasingly prevalent. For example, the capacitive touch sensing panels using capacitive sensing technology are widely used in a variety of hand-held electronic devices and equipment as human-machine interfaces. The conventional arcade games, such as pachinko or pinball, may apply capacitive sensing technology for more game-changing so as to offer users a lot more fun.

Abstract

The present invention discloses a position detection device including a first electrode layer, a second electrode layer, and a processor. The first electrode layer includes a plurality of first electrodes, and the second electrode layer includes a plurality of second electrodes. A gap is formed between the first electrode layer and the second electrode layer. The processor detects a plurality of capacitive values between the plurality of first electrodes and the plurality of second electrodes so as to measure the movement track of a conductive object passing through the gap.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 158,675, filed on May 8, 2015, and the benefit of Taiwan Application Serial No. 104144647, filed on Dec. 31, 2015, which are herein incorporated by reference for all intents and purposes.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a position detection device, and more particularly, to a position detection device detecting a conductive object therein.[0004]2. Description of the Prior Art[0005]Touch sensing panel has widely been applied to a lot of electronic devices. In general practice, a touch sensing panel placed on a touch display is defined as a two-dimensional touch sensing area for getting sensing information by scanning the vertical axis and horizontal axis on the touch sensing panel so as to determine an external object, such as a finger, touching or approaching the touch sensing panel. For example, a cap...
